TYPE-WRITING vMACHINE To all whom it may concern Be it known that I, LESTER A. WERNEBIY,

a citizen of the United States, residing in Type-Writing Machines, of which the following is a specification. I

This invention. relates to tabulating devices for typewriting machines and my improvement is particularly directed to a convenient method of attachment and release for such devices, whereby they may bereadily applied to and removed from the machine.

In practice, it is desired to change the setting of the colunm stops frequently, as demanded by different classes of work. Heretofore it has been the practice to readjust the column stops for each new kind of work; and in many cases this readjustment has to be doneseveral times for each page of writing.

One of the principal objects of my invention is to avoid this difliculty and save the labor and liabilities to mistake incident to frequent readjustment of the stops.

' According to my invention, there is provided a set of column-stop frames, each completewith its quota of adjustable column stops, and the construction is such that any frame may be readily detached from the machine and another frame substituted; the frame being preferably detachable at its pivot, and a detachable connection to the key being substituted for the usual permanent connection. The operator may have two, or three, or any number of these frames, and may adjust the column-stops thereon before placing the same on the machine: and the column-stops, when once adjusted along a frame, maybe allowed to remain where adjusted; it being only necessary, when desiring to change from one kind of tabulating work to another, to slip off the tabulating frame from the machine and substitute therefor another frame, having the desired adjustment column-stops thereon. Moreover, a small number of frames will answer for a great variety of work, inasmuch as Specification of Letters Patent.

Application filed February 18, 1914. Serial No. 819,346.

any set of stops may be readjusted on its frame from time to time, if required.

In carryin out my invention I employ a removable, pivotal stud adapted to enter a socket bearing therefor in one end of the rocker bar of a tabulating device as a support therefor, the said stud being yieldingly retained in a bearing in the machine frame by a spring clip device while in the aforesaid pivotal engagement with the tabulator,

the release of said spring clip enabling the.

removal of the stud.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a perspective rear elevation of a portion of a typewriter having a tabulator and showing my improved attaching and releasing device. Fig. 2 is a" top plan view of a tabulator. Fig. 3 is a side elevation of a tabulator with key actuating mechanism. Fig. 4 isv a detail perspective View of a tabulator support and releasing device. Fig. 5 is an enlarged detail section of the tabulator showing the connection therewith of the operating key.

The invention. is illustrated asapplied to the usual Underwood construction of typewriting machines, wherein 1 indicates the rear rail, slidably supporting carriage 2 carrying the platen, said rail being mounted on abutments 3 from brackets 4 which extend from the opposite upper corners of the machine frame.

The tabulator, which is in frame like form, composed of the lower rock bar 5, adapted for pivotal engagement with brackets 4, and upper bar 6 having depending rack teeth 7 together with end connecting \bars 8 for said bars 5 and 6, is provided with an intermediate rod 9, also secured to end bars 8, and serving as a support and slideway for stop devices 10, mounted on said rod 9, in a manner to both slide and swing thereon. Said stops 10 have teeth 10 for engagement with the rack teeth 7 when it is desired to set and look a stop at a predetermined position longitudinally on rod 9, the stops 10 also each having a finger or The stoplO which is adapted when inv from and being bent forwardly at its extremity to lie closely against a scale 11, extending along the upper surface of bar 6, said scale bearing marks indicating linear divisions with which .said pointer 10 may register, a handle. 10 upon stop 10 enabling it to be entered into and removed from engagement with rack teeth 7 as desired.

operative position to arrest the carriage through the action of a lug 12 on the carriage frame lying in its path, is normally inoperative because the tabulator is normally swung backwardly on its trunnions. as by a leaf spring 5 secured to bar 5 and exertmg tension against the upper surface of.

the frame. The tabulator has a bearing recess 5 in or near one end of its lower bar. 5 to receive a pivot 13which may be in form of a screw, entered through an orifice 4 in the bracket 4, on the corresponding side of the machine. The opposite lower end of the tabulator also has a bearing recess 5", with which is alined an orifice 4 in its adjacent bracket 4,where a quickly removable pivotal connection is provided. Said connection comprises a pivot 14 .adapted to enter tabulator,

orifice 4 and having a diminished forward portion '14 which extends inwardly from bracket 4 to enter the recess 5 when alined therewith upon fitting the tabulator in place.

To prevent accidental displacement of pivot 14, it has attached to its outer end a at spring member 15, which may be'secured to the outer end of pivot 14 as by screw 14". Spring 15 is bent at right angles,

providing an arm 15, from whose inner surplies a continuous endwise pressure on the pivot pin 14. This pressure, applied to the tabulator, holds'the latter on the pivot 13, the endwise position of the tabulator frame being determined by the adjustment of the pivot pin 13. To remove the tabulator from the machine it is only necessary to release in 16 from recess 16", when the pivot 14 can e withdrawn from engagement with the leaving the latter free for removal. y f

. The operation of the tabulator stop devices is controlled by a key lever 17, having pivotal engagement at its rear end with a transverse rod 18 and a tensional fulcrum at'17, said lever 17 having pin and slot conforwardly to bring the stops 10 in the path ofcarriage lug 12. The slot 19- in link 19 has an upper enlargement 19 to permit its removal over the head of stud 17 on lever 17 when it is necessary to disconnect the key lever from the tabulator to permit the removal of the tabulator.

Rock bar 5 hasa forwardly extending lug 20 which-bears upon the upper surface of a rock arm 21, fulcrumed at 21 to the frame and having a forward extension 21 carrying a wheel or .rol1er 22 which supports the usual carriage feed rack 23, that is mounted on pivotal arms 23*, of which only one is shown in the drawing. Said feed rack is shown in' Fig. 3', in engagement with pinion 24 having escapement wheel 25 controlled by the usual feed device 26.

Consequent upon the depression of key lever 17, the tabulator will be rocked forwardly through link connection 19, in which action rock arm 21. being depressed by lug 20 will cause its extension 21 to elevate roller 22 which in turn will raise feed rack 23 out of mesh with pinion 24, leaving the carriage free to travel along its rail 1 and to be controlled by the tabulator stops instead of by theusual feed device's.

To render the pivot member 14 capable of adjustment axially, the spring 15 may be embraced by nuts 14 at each sidethereof on screw 14", and the member 14 may be screwed in or out upon'screw 14 to enable it to correspond with the adjustment of pivot 13 independently of the lock 16.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
